ddns-updater VS ddclient

Setup https://github.com/qdm12/ddns-updater to keep you IP address updated for your Google DNS record. This is only need for inbound access while you are remote so that your DNS record is updated if you IP address changes.

Do you mean something like ddns-updater?

This assumes you have your DynDNS mechanism set up by any means other than the Fritz!Box internals (for example, I use this docker image, in combination with my cloudflare managed domain to achieve DDNS behavior). This means that the Fritz!Box needs to be reachable with the domain you intend to use for your VPN connection. For example, I use vpn...

SOLVED: Thanks to some of the suggestions here I realized the WAN IP wasn't actually changing. The DDNS updater I use: https://github.com/qdm12/ddns-updater uses a bunch of different sources, both http and DNS to determine the current public IP. At lease one of the http sources was no longer working and I have no idea how the DNS sources are supposed to know what my current IP is, that doesn't make sense to me.

I use ddns-updater.

Take a look at qdm12/ddns-updater

Use https://github.com/qdm12/ddns-updater. You can buy a standard domain, and this will keep it pointed at your IP.

if youre public IP isnt static, you will need a dns-updater too.

Use a dynamic DNS service like noip.com. You either use one of their domains like myusername.someDDNScompany.com or you use your own domain. Then you run software like ddns_updater on a raspberry pi or a docker container on your NAS that periodically checks and updates the DNS record with your current home IP.

You can find an example of the full config file here: https://github.com/ddclient/ddclient/blob/master/ddclient.conf.in

Check your distribution's repos first, but Ddclient doesn’t have an automatic installation procedure. Get the tar-file from https://github.com/ddclient/ddclient/releases and untar it. Copy the perl script to your favorite location (ex. /usr/sbin) and create a

ddclient has support for Google DNS. It is available as a package on Ubuntu/Debian.

As I recall ddclient is a perl script or some such. It should be relatively easy to just download and build it. https://github.com/ddclient/ddclient/releases

Which version of OPNSense are you running at the moment? There were changes to the os-ddclient package in the 23.1.6 patch in order to fix the config generation in response to changes in ddclient 3.10.0 when enabling IPv6 updates (ipv6=yes was disabled, and replaced with usev4/usev6. If a reboot doesn't help, I'd be happy to give you a hand with debugging the ddclient config.

So a came accros Inadyn which compared to the current state of DDclient, is being actively maintained. More info here from what i am talking about.

You can use ddclient, it supports a lot of DNS providers: https://github.com/ddclient/ddclient
